Hi,

I convert a recipient mailbox to a shared mailbox and grant permission for few users using the O365 portal under "Mail Delegation - Full Access" and also tried using powershell:

add-mailboxpermission -identity XXX -user MYACCOUNT-accessrights fullaccess

I tried to open it using outlook 2016 (account- change- advanced) and also using the OWA ("open another mailbox") but im receiving the following errors:

"You don't have permission to open this mailbox"

client-request-id: XXXX
X-OWA-Error: SDServerErr;Microsoft.Exchange.Data.Storage.ConnectionFailedTransientException
X-OWA-Version: 15.1.888.8
X-FEServer: DB5PR02CA0029, VI1PR0101CA0002
X-BEServer: DB6PR0701MB2087.eurprd07.prod.outlook.com
Date: 1/30/2017 9:15:44 AM
InnerException: Microsoft.Mapi.MapiExceptionLogonFailed

Please help me solve it, Thanks !

    How long has it been since you added the permission?

    Are you running only Office 365, or Hybrid with On-premises Exchange?

    Hi,

    Be aware that it can take a little bit of time for the changes you've made to fully take effect.

    In the meantime, you can double check the permissions are correct by running

    Get-MailboxPermission -identity XXX

    and see that the correct permissions have been assigned to the user.

    Let me know how you go.

    Liam
